Time		7E model
4-4:10 Arthur	Go over homework from Week 2 (fast and minimal) Homework Section 3 Read – Physics Talk Read – Active Physics Plus Physics to Go 1,2,3,4,6,9 Section 4 Answer the Essential Questions on p67 Physics to Go 1,2,11,12	Evaluate
4:10-5:00 Arthur	Crucial Physics from Sections 5-7 that the teachers completed at home due to snow day. Section 5 – stopping distance Stopping distance proportional to vel squared Show ramp: twice the speed; 4x the stopping distance Thrice the speed: 9x the stopping distance Section 6 – Yellow Light Show go zone and stop zone at intersection Why do these equations make sense? D(go)=vt(y)-w D(stop)=vt(r) + v^2/2a Section 7 – circular motion F=mv^2/R Force is friction V^2 dependence again Discussion of no class and no investigation – what was lost; comparison to class with students Discussion of homework for Lesson 3 (fast and minimal) Section 5: Physics to Go, #1, 2, 3. Section 6: Physics To Go, #1, 2, 3, 4 Section 7: Essential Questions on p.113 and Physics to Go, #4, 9.	Explain Extend Evaluate
